 Another thing I'd like them to explain is how they determine whether

pilot wants economy cruise at altitude or best power (to climb over an
aproaching mountain or weather).  The throttle is in the same position

(wide

open) for both cases.  The only difference is mixture control.  If it

is a

single lever power control, how the hell does the controller know what

the

pilot wants?  I asked this question to the people at PowerSport (who

also

use a pseudo FADEC system).  They couldn't give me an answer then but
promised to get it for me.  I'm still waiting.

Well, the throttle may be in the same position in a conventional

aircraft setup

(separate throttle and mixture), but presumably in a FADEC system, the

pilot puts

the lever at full power for climbing over the mountain, and some lesser

position

for economy cruise (at altitude).  The lever is no longer a "throttle"

per se, but

rather a "power demanded" indicator.  This assumes that the lever isn't

attached

to anything other than an encoder for the FADEC.

Your assumption is correct but none of the controllers under discussion is
setup this way.  They are not "fly by wire" systems.
